CHILACHAP, a port in Java, Dutch East Indies, on the south coast, in the residency of Banjumas, to the left of Schild padden bay. Its harbour, the most favoured by nature in the whole of Java, is formed by the island of Nusa Kambangan, which is long and narrow, and lies close to the shore opposite Chilachap, beyond which it projects for a considerable distance and thus protects it from the heavy monsoon seas and swell of the Indian ocean. With the exception of Segoro Wedi bay, Chila chap is the only harbour on the south coast of Java which affords protection during the south-east monsoon, and it is the most important. The town of Chilachap, which has a population of 147,605, including 790 Europeans and Eurasians, and 2,258 foreign Asiatics, stands on a tongue of land flanked on the east by Schilpadden bay, and on the west by the estuary of the river Donan. The entrance to the harbour, which is fortified, is be tween a projecting headland of Nusa Kambangan and South Point, on the tongue of land opposite, and is one and a half miles wide, but owing to a sandbank, the navigable channel, which varies in depth from 29f t. to 48f t., is narrow. At present the port has two concrete wharves, 1,350ft. and 400ft. in length, respec tively, affording mooring-places for vessels drawing up to 23ft. of water at low tide, and a dredging scheme is in hand which will increase the draught to 3of t. Chilachap is connected by rail with Batavia, Surabaya, Surakarta, and Samarang by a junction with the main Batavia-Surabaya line at Maos. In 1922 the total ton nage of vessels clearing from the port was 317,765. Imports and exports, respectively, were, for Chilachap in 1927, 5,460,951 and guilders.
